Detailed Description

Referring to fig. 1 to 4, the portable dustless sander of the present invention comprises a sander body 1, wherein the sander body 1 comprises a housing and a sanding disc, and the sanding disc is located below the housing; the polishing machine is characterized in that a lantern ring 2, a protective cover 4 and a shielding plate 3 which are sequentially arranged from top to bottom are additionally arranged, the lantern ring 2 and the protective cover 4 are coaxially arranged with the polishing machine body 1, the lantern ring 2 is fixed on the outer surface of the shell in a sealing mode, the fixation can be detachable or non-detachable, detachable fixing structures such as bolts and buckles are preferably adopted, the sealing is achieved through low-grade sealing, and dust cannot leak when polishing is guaranteed; the lantern ring 2 is provided with an annular wall 21 which is coaxial with the sander body 1, the annular wall 21 can be a circular ring, a square ring and the like, preferably, the circular ring is adopted, the sander is more adaptive, and manufacturing raw materials are saved; the lower terminal surface of annular wall 21 is equipped with the annular groove coaxial with polisher body 1, guard shield 4 includes installation department 41 and dodges portion 42, installation department 41 is the tubular structure, installation department 41 inlays the dress and is in the annular groove, installation department 41 can be in the annular groove along the axial sliding regulation and dispose locking mechanism 16, locking mechanism 16 adopt common bolt, buckle isotructure can, installation department 41 slides when supreme extreme position the polishing dish expose in guard shield 4's below, dodge portion 42 for expanding the column structure outward, the polishing dish is located dodges portion 42 when installation department 41 slides to lower extreme position, guard shield 3 shields the lower opening of guard shield 4 completely in order to form the enclosure space, and guard shield 3 can dismantle fixedly with guard shield 4. When the grinding machine is used, the protective cover 4 is pushed up to the upper limit position and is locked by the locking mechanism 16, the grinding disc is exposed below the protective cover 4 at the moment, grinding operation can be carried out, and the protective cover 4 plays a role in safety protection; when the sander is not used, the protective cover 4 is pushed to the lower limit position and is locked by the locking mechanism 16, the sanding plate is positioned in the avoiding part 42, the shielding plate 3 is attached to the lower surface of the avoiding part 42 and is detachably fixed with the protective cover 4, and therefore one end of the sander used for sanding is protected and prevented from being damaged during moving or transporting.

As a preferred connection mode of the shield 4 and the shield 3, the lower end portion of the shield 4 extends radially outwards to form an annular connection portion 43, a connection area 31 radially exposed out of the connection portion 43 is formed when the shield 3 is attached to the lower surface of the shield 4, at least three fixed cylinders 5 are fixed on the upper surface of the connection area 31, the at least three fixed cylinders 5 are uniformly distributed in an annular array form coaxial with the sander body 1, a clamping rod 6 is hinged in each fixed cylinder 5, a hinge shaft is perpendicular to the shield 3, a compression screw 17 arranged up and down is arranged at the end portion of the clamping rod 6, and the length of the clamping rod 6 and the height of the fixed cylinders 5 jointly satisfy the condition that the compression screw 17 can be compressed on the upper surface of the connection portion 43 through the rotation of the clamping rod 6 around the fixed cylinders 5. In a non-working state, when the shield plate 3 needs to be installed, the shield plate 3 is attached to the lower end face of the shield 4, then the clamping rod 6 is pushed to rotate around the fixing cylinder 5 until the compression screw 17 is arranged above the connecting portion 43, then the compression screw 17 is screwed, the compression screw 17 abuts against the upper surface of the connecting portion 43, and the connection between the shield 4 and the shield plate 3 is completed.

As an optimal structure of the lantern ring 2, the lantern ring 2 is a barrel-like structure integrally formed by an annular wall 21 and a mounting ring 22, the barrel-like structure is formed by opening a hole in the center of a base plate of the barrel body, the mounting ring 22 is located at the upper end of the annular wall 21, an inner hole of the mounting ring 22 is a circular hole in the center of the base plate of the barrel body and is matched with the shell, and the mounting ring 22 is screwed and fixed on the shell through a plurality of circumferentially and uniformly distributed bolts. The existing sander housings are all provided with horizontal end faces which can just fit the mounting ring 22 and then be connected through bolts. Here, the sealing is only required to be locked by bolts and the like, the sealing grade is required to be low, and as long as no gap is left and dust is prevented from leaking, which is the common knowledge of the design of the outer cover of the sander by the personnel in the field.

Preferably, the locking mechanism 16 is a plurality of groups of locking bolts uniformly distributed on the outer side surface of the annular wall 21, and has a simple structure and is firmly locked.

Further, the upper portion external surface of casing is fixed with connecting cylinder 7 that two symmetries set up, the axis perpendicular to casing surface of connecting cylinder 7, every connecting cylinder 7 all compresses tightly through adjusting screw 9 has a pole setting 8, pole setting 8 is perpendicular with connecting cylinder 7 axis, and two pole settings 8 are parallel to each other and the upper end passes through horizontal pole 10 and links to each other, be fixed with two slide rails 12 on the horizontal pole 10, two slide rails 12 all with horizontal pole 10 parallel and symmetric distribution, all inlay on every slide rail 12 and be equipped with a slider 13 and dispose the retaining member, the retaining member preferably adopts the bolt, all is fixed with the leader 14 on every slider 13. When the device is used, the upright rod 8 can be pushed to rotate around the axis of the connecting cylinder 7 so as to adjust the operation angle, and the adjusting screw 9 is screwed after the operation angle is adjusted to a proper angle so that the upright rod 8 is tightly pressed on the connecting cylinder 7; can promote slider 13 and remove in order to adjust the both hands interval on slide rail 12, through retaining member locking slider 13 when to suitable interval, when convenient to use person polishes the wall, adjust handle 14 to convenient to use's position to strengthen user's use comfort. The problem of current portable dustless polisher handle 14 rigidity, only can keep fixed posture to polish the wall body, when polishing the roof wall, often polish the posture comparatively uncomfortable, have the limitation is solved. Specifically, two connecting blocks 11 may be symmetrically fixed on the cross bar 10, and then two sliding rails 12 may be fixed on the connecting blocks 11, respectively.

Preferably, the locking member is a clamping bolt 15.
